SAFETY-BOTTLE.

Specification of Letters Patent.

Patented May il, 1916.

Application vled July 17, 1915. Serial No. 40,428.

To all whom it may concern Be it known that l, OSCAR S. HAsLn'r'r, acitizen of the United States, and a resident of Jersey City, in thecounty of Hudson and State of New Jersey, have invented a new andlmproved Safety-Bottle, of which the following is a full, clear, andeXact description.

This invention relates to bottles, jars, etc., and has particularreference to safety closures for bottles. By the term bottle as usedhereinafter I wish to be understood as covering any type of container towhich my device is applicable.

Among the objects of the invention, more delinitely stated, is toprovide a safety closure or stopper for bottles used especially forcontaining poisons or other dangerous materials, and whereby a personwill be prevented from accidentally opening the bottle and partaking ofany of the contents thereof under the mistake or misapprehension that heis taking something else. Many fatal results occur from persons takingpoison at night or under such conditions that they are not caused to bethoroughly aware of the danger existing, and by providing a closure forthe bottle which will require light and a certain amount of care andcaution to open it, the danger from accidents will be overcome.

With the foregoing and other objects in view, the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed herein, still for the purpose of illustratinga practical embodiment thereof reference is had to the accompanyingdrawings, in which like reference characters designate the same parts inthe several views, and in which- Figure 1 is a side elevation of apreferred form of stopper or closure; Fig. 2 is a vertical sectionalview of the bottle neck and mouth; Fig. 3 is a transverse section on theline 3dS of Fig. 2, but on a larger scale and the parts having beenrotated; and Fig. 4 is a perspective view indicating the bottle with thestopper in closed position.

Referring more particularly to the drawings, l show a speciallyconstructed stopper 10 comprising a knob 11, a shank 12 and anintermediate conical portion 13 which may be ground or otherwise truedto lit into the mouth of the bottle. The lower end of the shank 12carries an outwardly projecting lug 14, and the upper portion of thestopper, either at the knob or at the top of the cone 13, is formedwithan indicating mark 15 representing the vertical plane of the lug 14.

The bottle neck 16 is formed with an inner annular shoulder 17 open orbroken at 17 at one or more points. The clear space within the shoulder17 is substantially the same or slightly larger than the diameter of theshank 12, and the stopper' may be readily admitted into its place whilethe lug 14 passes downwardly through the opening 17 At 18 is indicated aseries of spaced parallel lingers or their equivalent extendingdownwardly from the shoulder 17 and of substantially the same radialthickness as said shoulder. The spaces between the lingers aresubstantially the same in width as the width of the lug 14: and hencewill readily admit the lug between them, but the lug 14 impingingagainst the lower edge of the shoulder 17 will prevent the withdrawal ofthe stopper. It is therefore necessary, in order to remove the stopper,that it be rotated until the lug 14 registers vertically with theopening 17 at which time the stopper may be freely withdrawn.

At 19 is an indicating mark applied to the bottle neck in verticalalinement with the opening 17. rlhe operator may know, therefore, thatwhen the two indicators 15 and 19 are brought into registry with eachother a similar condition obtains with respect to the lug let andopening 17. Then the stopper is inserted into the bottle, under ordinaryconditions, it is given a partial rotation after the cone 13 is seated.It follows, therefore, that it will be practically impossible for thestopper' to be withdrawn under such conditions that the operator is notusing his eyes and his wits, although when light is present and theoperator understands the structure of the bottle, no difficulty and nodelay are experienced in removing the stopper.

I claim:-

1. The combination with a bottle neck having an inwardly projectingannular shoulder, said shoulder being provided with a vertical openingand also having a series of spaced fingers projecting downwardly fromthe shoulder, and a stopper adapted to fit into the neck and having alug projecting outwardly therefrom and adapted to register with and passfreely through said adapted to coperate with said mouth, said shank alsohaving an outwardly projecting lug adapted to pass into the opening insaid shoulder aforesaid and lie beneath said lingers when the stopper isseated, said lug upon rotation of the stopper being adapted to bereceived between adjacent fingers, and indicating means to enable theoperator to register the lug with said opening.
